Arduino IDE
Arduino IDE library
This repository contains the source code of the Arduino IDE 2.x, which is currently in the beta stage. The Arduino IDE 2.x is a major rewrite, sharing no code with the IDE 1.x. It is based on the Theia IDE framework and built with Electron. The backend operations such as compilation and uploading are offloaded to an arduino-cli instance running in daemon mode. This new IDE was developed with the goal of preserving the same interface and user experience of the previous major version in order to provide a frictionless upgrade. If you need assistance, see the Help Center and browse the forum. If you think you found a vulnerability or other security-related bug in this project, please read our security policy and report the bug to our Security Team. The builds are generated every day at 03:00 GMT from the main branch and should be considered unstable. -

Node-RED provides a browser-based flow editor that makes it easy to wire together flows using the wide range of nodes in the palette. Flows can be then deployed to the runtime in a single-click. JavaScript functions can be created within the editor using a rich text editor. A built-in library allows you to save useful functions, templates or flows for re-use. The light-weight runtime is built on Node.js, taking full advantage of its event-driven, non-blocking model. This makes it ideal to run at the edge of the network on low-cost hardware such as the Raspberry Pi as well as in the cloud. -

Windows 95 in Electron
Windows 95 in Electron. Runs on macOS, Linux, and Windows
windows95 in Electron is a quirky, nostalgia-driven project that ports a complete emulation of Microsoft Windows 95 into a desktop application that runs on modern operating systems like Windows, macOS, and Linux. It essentially wraps an emulator — preconfigured to boot Windows 95 — inside a user-friendly app built with web technologies so developers and hobbyists can explore the look and feel of that classic OS without needing legacy hardware or complicated setup. Users can interact with familiar UI elements like the Start menu, File Explorer, and retro applications in a sandboxed environment that evokes early personal computing. Beyond being a playful trip down memory lane, the project demonstrates how emulation can be packaged using modern frameworks & how legacy operating systems can be encapsulated as distributable desktop experiences. It’s become an example of how software preservation and creative programming can intersect, inspiring others to bring historic systems to life. -

AutoAP
A script to find open Wi-Fi connections and the strongest signal
AutoAP is a script that continuously scans for open Wi-Fi connections, tests them for validity, and connects to the strongest signal. If the connection is lost, the script scans again and finds the strongest valid signal again, and maintains a continuous connection to the internet in a mobile or portable environment. The script paremeters are highly configurable, including ability to configure secure connections. AutoAP is an add on to DD-WRT that allows routers to continuously scan for and connect to open (and predefined WEP) wireless networks. Ultimately the goal is to develop an easily deployable firmware that facilitates fast and easy mesh network creation. Typically, you would use this script on your router while in Repeater Mode, Client Mode, or Client-Bridged Mode. -

chromeos-apk
Run Android Apps in Chrome OS OR Chrome in OS X, Linux and Windows
Make sure Android applications are compatible with your Chromebook, first try to install an official application. Download an official app, such as Evernote, from the Chrome Web Store. Then download an open source game, like 2048.APK Game by Uberspot and load it as an unpacked extension. Go to chrome://apps and launch it there, ignore warnings. Install a sample Android app from the Chrome Store to get the runtime. Test out that app, make sure it runs on your hardware. Ubuntu might need sudo apt-get install lib32stdc++6. Install Node.js and install the tool (might need a sudo prefix). With Chrome 38+ you can now side load as many applications as you want. If you have older apps that were created using chromeos-apk tool then re-convert them or remove the "key" option from manifest.json. -

AnduinOS
AnduinOS is a custom Ubuntu-based Linux distribution
AnduinOS is a personal/experimental operating system–style project and collection of components built to explore how a desktop-like environment and tooling could be organized under one coherent repo. It combines configuration, scripts, and UI elements to form a workstation experience that is more opinionated and automation-friendly than a vanilla setup. The project leans toward developer productivity: quick access to tools, reproducible configuration, and a unified place to evolve the environment. Because it is open source, users can inspect how the author wires services, handles packaging, or defines UI/UX conventions. It’s well suited for people who want to understand how to bootstrap and maintain a bespoke, code-driven desktop environment rather than relying on distro defaults. Over time it can serve as a living example of infrastructure-as-code principles applied to a personal OS setup. -

Twinkle Tray
Easily manage the brightness of your monitors in Windows
Twinkle Tray enables brightness control on external displays in Windows 10 & 11.
